GEORGE F. MART N BY 'A;%JV EY United States Patent 3,172,534 CONTAINERFOR PACKAGING YARN ON SPOOLS OR BOBBINS George F. Martin, Cincinnati,Ohio, assignor to The Mead Corporation, Dayton, Ohio, a corporation ofOhio Filed Oct. 27, 1961, Ser. No. 148,181 1 Claim. (Cl. 20665) Thisinvention relates to a method and container for packaging yarn on spoolsor bobbins.

Generally, there is provided a carton formed from a single rectangularblank of corrugated cardboard or the like and having a row of panelsfoldable about vertical scored fold lines to define the side and endpanels of the carton. The top and bottom edges of the side and endpanels have overlapping closure flaps integrally connected thereto alongscored hinge fold lines. The top and bottom closure flaps have evenlyspaced aligned apertures therein which protectively and accuratelyposition spools or bobbins of yarn. The upper bare ends of the spoolsproject upwardly through the apertures in the upper carton closure andaxially into the hollow bases of spools or bobbins in a like cartonstacked thereon in a shipping container holding a plurality of tieredcartons arranged in one or more rows.

It is an object of the present invention to provide a simple, efiicientand economical method and means for packaging yarn wound on conicalhollow spools in which a plurality of rows of the wound spools arepackaged in cartons having aligned apertures in top and bottom closureflaps for protective positioning of the spools thereby and by atelescopic interengagement produced by the necks of the spools in onecarton projecting through aligned carton apertures into the hollow basesof spools in a superimposed like carton.

It is another object of the invention to provide a carton of the typedisclosed formed economically from a single rectangular foldable blank.

It is a further object of the invention to provide a carton of thecharacter described having overlapping top and bottom flaps held inalignment by, and holding properly spaced and in alignment, rows ofconical bobbins having bare necks extending upwardly through theapertures in the top closure flaps and through the bottom apertures of asuperimposed like carton.

It is still another object of the invention to provide a plural cartonpackage in which the cartons of the bottom layer are provided, ifdesired, with spacers to prevent relative spool movement.

Other and further objects of the invention will become apparent from areading of the following specification, taken in conjunction with thedrawings, in which:

FIGURE 1 is a plan view of a die cut and scored blank for one of thecartons;

FIGURE 2 is a perspective view of one of the cartons ready for fillingwith spools of yarn;

FIGURE 3 is a perspective view of a closed but empty carton;

FIGURE 4 is a perspective view illustrating the packing of rows andtiers of the cartons in a shipping container;

FIGURE 5 is an elevational view, in section, taken on line 55 of FIGURE4;

FIGURE 6 is an enlarged fragmentary elevational view showing thetelescopic nesting interengagement between the spools of stackedcartons;

FIGURE 7 is a perspective view of the closed package of FIGURE 4; and,

FIGURE 8 is a perspective view showing eight containers mounted on ashipping pallet.

With reference to FIGURES 1, 2 and 3 of the draw- 3,172,534 PatentedMar. 9, 1965 ice ings, numeral 10 generally designates a rectangular diecut and scored rectangular blank of corrugated cardboard or equivalentmaterial. Three vertical parallel scored fold lines 11, 12 and 13 dividethe blank 10 into a horizontally extending row of edge-joined panels 14through 17. Panels 14 through 17 are foldable, as best seen in FIGURE 2,to define the circumferentially continuous side and end walls of acarton, generally designated 18, when the free ends 19 and 20 of theextreme panels 14 and 17, respectively, are abutted at the corner 21 ofcarton 18. The joint at 21 may be maintained closed solely by the effectof the overlapping closure panels hereinafter described, or optionallyby a strip of adhesive tape (not shown) extending along and bridging thejoint 21.

Scored hinge fold lines 22 and 23 and die cut slits 24 define topclosure flaps 25 through 28 and bottom closure flaps 29 through 32.

In the disclosure of FIGURE 2, bottom closure flaps 29 through 32 havealready been folded to produce the bottom of the carton in a mannersubstantially identical to the folding of top closure flaps 25 through28, as illustrated by FIGURES 2 and 3. The end closure flaps 26 and 28are first bent horizontally toward each other, after which the longerclosure flaps 25 and 27 attached to side panels 14 and 16, respectively,are folded down over flaps 26 and 28.

The longer closure flaps 25, 27, 29 and 31 are provided with rows ofequally spaced apertures 33 positioned for vertical alignment of theapertures in the upper closure flaps with those in the lower closureflaps. The shorter closure flaps 26, 28, and 32 are also provided withapertures 34 of the same size and spacing and positioned so as to alignthe upper and lower apertures 34 both with each other and also the endapertures 33 of the overlapping longer flaps 25, 27, 29 and 31, as shownbest in FIGURES 3 and 6.

FIGURES 4, 5 and 6 show how rows of spools or bobbins having yarn woundthereon are packaged in cartons 18 and how a plurality of said cartons(nine in the illustrative example of FIGURES 4 and 5) can be packaged inrows and tiers in a master container or carton of conventionalconstruction, generally designated 35. Spools or bobbins, generallydesignated 36, each comprise a conically tapered tubular spindle 37formed of laminated paper or other suitable material. Yarn 38 is woundon each spindle 37 in a predetermined amount and to a predetermineddiameter and also so as to leave free of yarn a considerable portion ofthe upper smaller end of each spindle 37 to constitute a bare neckportion 39 of a length sufiicient to extend upwardly through the alignedapertures 33 and 34 of top closure flaps of carton 18 in which spools 36are packaged and also upwardly through the aligned apertures 33 and 34of a similar superimposed carton 18. A neck portion 39 telescopicallyenters a hollow base 40 of a spool spindle 37 in said superimposedcarton (FIGURES 5 and 6).

Since the cartons in the bottom row, or in other words the bottom cartonof each tier, do not have neck portions 39 projecting upwardly into thebases 40 of spindles 37 contained therein, it is desirable to employspacing means, such as strips 40' of corrugated cardboard positionedvertically between adjacent spools 36 so as to prevent movement of theirlower ends during handling or shipping of the packaged spools.

To facilitate packaging of cartons 18 in the master container 35, endpanels 15 and 17 of each carton 18 may be provided with die cut handopenings 41 which form handles.

FIGURE 7 shows how the master container 35, having packed therein nineof the cartons 18, is closed and sealed by the use of strips 41 ofadhesive tape. In FIGURE 8, four master cartons are shown mounted upon apallet, generally designated 42, fastened thereto by metallic straps 43for convenient handling and shipping,

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed is:

A package comprising a master container, a plurality of horizontallyarranged rows of cartons, each of said rows being in vertically stackedrelation, a plurality of bobbins of yarn or the like therein wound onspool spindles in each carton, said spindles being upwardly taperedtubes the lower ends of which extend somewhat below the lower surfacesof said bobbins and the upper ends of which extend upwardly for aconsiderable distance above the upper surfaces of said bobbins and whichare of a diameter snugly telescoping into the bases of like spindlesaxially disposed in cartons thereabove, said cartons each comprising ablank of relatively still sheet material die cut and scored to define arow of edge-joined panels foldable to form the side and end walls ofsaid carton and a plurality of top and bottom closure flaps hingedlyjoined along scored fold lines to said side and end wall panels, saidclosure flaps having rows of substantially equally spaced verticallyaligned apertures therein of a size snugly receiving the upper exposedends of said spindles therethrough to protectively and accurately spacesaid bobbins in said carton, said apertures being of diameters somewhatsmaller than the outside diameters of the base ends of said spindles,whereby said bobbins are held protectively spaced from the bottom ofsaid carton, and means for spacing and holding against relative movementthe lower ends of said bobbinsrin the lowermost carton of each row ofcartons, said means comprising strips of sheet material extendingvertically between and in abutting relation to the lower portions ofadjacent bobbins and rows thereof in said lowermost cartons.
